When the amount of active substance is constant, the geometric area of the electrode plate in direct contact with the electrolyte increases, resulting in an increase in battery capacity. Therefore, the influence of the geometric size of the electrode plate on battery capacity cannot be ignored
① The Effect of Plate Thickness on Capacity
The amount of active substance is constant, and the battery capacity decreases with the increase of electrode plate thickness. The thicker the electrode plate, the smaller the contact surface between sulfuric acid and active substance. The lower the utilization rate of active substance, the smaller the battery capacity
② The Influence of Plate Height on Capacity
In a battery, there is a significant difference in the utilization rate of active substances between the upper and lower parts of the electrode plate. Experiments have confirmed that in the early stage of discharge, the current density in the upper part of the electrode plate is about 2 to 2.5 times higher than that in the lower part. This difference gradually decreases with the passage of discharge, but the current density in the upper part is greater than that in the lower part
③ The Influence of Plate Area on Capacity
When the amount of active substance is constant, the larger the geometric area of the electrode plate, the higher the utilization rate of the active substance, and the larger the capacity of the battery. When the battery shell is the same and the quality of the active substance remains unchanged, using a thin electrode plate to increase the number of electrode plates increases the effective reaction area of the electrode plate, thereby improving the utilization rate of the active substance and increasing the capacity of the battery.
